Modeling Methods for Discrete Choice Analysis

This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems.     

Agricultural disaster payments in the southeastern US: do weather and climate variability matter?

Governments around the world are forced to react to disasters caused by weather. The agricultural sector is particularly susceptible to weather extremes and adverse climate conditions. In the US, agricultural disaster payments account for a significant part of total agricultural subsidies. The payments, and their distribution, are more important in the areas most affected by disastrous weather events, usually coinciding with areas of pronounced impact of the El Nino Southern Oscillation (ENSO). In this article, the impact of weather and climate, as well as some economic variables, on disaster payments is analysed using county level data from four states in the southeastern United States. The results suggest that weather and climate variables explain most of the crop disaster payments at the county level while socioeconomic variables do not, suggesting that advancements in weather and climate forecasts could be helpful in planning for disaster compensation.     

An Empirical Study of Service Quality Implementation

The strategic importance of quality management has grown in importance in recent years. However, although the competitive implications of adhering to a quality agenda have been much alluded to within the literature, the evidence from a review of published studies suggests that service quality and strategy issues have been addressed as separate concerns by researchers. This study examines the components which facilitate the quality implementation process. The factor analysis of data emphasises the importance of ‘senior managerial commitment’ and ‘employee resourcefulness’ in quality implementation initiatives and offers support to the growing implementation initiatives and offers support to the growing literature arguing for a greater consideration of the human dimension in quality implementation programmes. It is proposed that further research needs to be carried out to examine mangerial attiudes towards the service quality implementation process and to assess some of the practical issues involved in introducing quality initiatives in hotel organisations.

ANALYSIS OF THE CURRENT ACCOUNT POSITION OF FOUR ASIAN COUNTRIES BEFORE THE 1997 CRISIS

Abstract.  The current paper presents an empirical analysis of the current account positions during the pre Asian crisis period, in the four most crisis-hit countries (namely Thailand, the Philippines, South Korea and Indonesia). We have employed the procedures advocated by Husted for the presence of stationarity in current accounts by estimating a cointegration relationship between any country's exports and imports. The results do not substantiate the presence of cointegration between the series, implying that the macroeconomic fundamentals in these countries prior to the crisis were far from robust, at least from the perspective of current account sustainability.     

企业社会责任学说的兴起与发展

企业社会责任思想起源于古典经济学理论，在争论和实践中不断发展与完善，20世纪80年代，现代企业社会责任运动开始在欧美发达国家逐渐兴起，并进入条文化阶段，到2000年，全球共有246个生产守则，成为规范企业行为的核心理念。     

The use of Web sites as a disclosure platform for corporate performance

Adopting a stockholders' interests' perspective, we explore three related questions: (1) What are the scope and patterns of corporate performance disclosure on the Internet? (2) What are the determinants of the extent and scope of corporate performance disclosure on the Internet? (3) Is corporate performance disclosure on the Internet relevant for valuation of a firm's earnings? Corporate performance disclosure relates to corporate actions and initiatives that directly affect society and, ultimately, stockholders' wealth. We focus on Web (HTML) disclosure. Our sample comprises Canada's largest publicly-traded firms, many of which are also SEC registrants. The extent and scope of web disclosure by these firms is rated using a coding grid. Regarding the first question, three disclosure patterns emerge: (1) firms providing disclosure about innovation, development and growth also tend to report about customer value as well as maintaining a Web site with good capabilities (business-related disclosure), (2) disclosure about human/intellectual capital is linked to social responsibility disclosure (social-related disclosure) and, (3) the disclosure of financial performance and corporate governance practices are both closely linked together (financial-related disclosure). Regarding the second question, firms apparently take into account variables proxying for information costs and benefits accruing to stockholders when determining the extent of their Web disclosure. Finally, regarding the third question, a firm's web-based performance disclosure appears to affect its earnings valuation multiple, although in a differential manner according to the nature of the information being conveyed.     

Drainwater Management for Salinity Mitigation in Irrigated Agriculture

Salinity and drainage management options include source control, reuse, and evaporation ponds. This article identifies efficient strategies to maintain hydrologic balance in closed drainage basins and evaluates their impact on regional agricultural profits. Theoretical analysis suggests that economic efficiency requires acknowledgment of the nonseparability between water use and land value. Empirically, our solution involves a modest amount of source control, a substantial amount of reuse, and the elimination of evaporation ponds often associated with large environmental damages, while maintaining grower income. Various policy instruments and options are introduced and discussed, including a system of drainwater charges, marketable permits, and land retirement.     

On Jumps and ARCH Effects in Natural Resource Prices: An Application to Pacific Northwest Stumpage Prices

Continuous-time models of natural resource prices usually preclude the possibility of large changes (jumps) resulting from unexpected events. To test for the presence of jumps and/or ARCH effects, we combine bounds and the Monte Carlo test technique to obtain finite-sample, level-exact p -values. We apply this methodology to stumpage prices from the Pacific Northwest and find evidence of jumps and ARCH effects. To assess the impact of neglecting jumps on the decision to harvest old-growth timber, we develop an autonomous, infinite-horizon stopping model for which we provide a new method of resolution. Our numerical results show the importance of modeling jumps explicitly.
